(Fig. 10)

Toxoscelus rugicollis Saunders 1874: 322 ; Obenberger 1934: 805; Bellamy 2008: 1739.

Original description. “ Purpureo-aeneus, thorace foveolato, lateribus rotundatis postice attenuato. Elytris maculis quibusdam supra medium, et postice fasciis duabus valde sinuatis, griseis ornatis. Subtus punctus. Bronzy, with a purplish tint. Head concentrically rugose and punctured, with a small round impression near the vertex. Thorax with the sides much rounded in front, and then converging rapidly in nearly straight lines to the base, which is deeply bisinuate. Surface concentrically rugose and punctured, with an oval transverse depression on the disk below the anterior margin, and a rather large somewhat kidney-shaped impression, just above the base, near each posterior angle; there is also a very slight depression near the front angles. Elytra much wider than the base of the thorax, sides sinuate, apex rounded, each with a band near the base, a round spot near the suture and an oval one at its side, above the middle, and two strongly zigzag bands; one just below these, the other midway between it and the apex, grey pubescent. Beneath and legs punctured, posterior tibiae hairy along their outer margin. Length 2 1/4 lines; breadth 3/4 line.”

Specimen examined. Holotype (BMNH): [ Philippines] Central Luzon.

Remarks. This species does not closely resemble any of its congeners from the Philippines, differing as indicated in the species key above. It has a more iridescent purplish integument color with a pattern of adpressed white setae on the elytra more reminiscent of species of Neotoxoscelus in the Philippines, but is kept in Toxoscelus by virtue of the character states of the legs which immediately separate these genera.
